Is polymorphism another term for overloading?

Question

Accepted Answer

No; overloading is creating a method with the same name with a different amount of parameters, or with parameters which are of another type.

Polymorphism is about changing the implementation / functionality of a specific method across various types (which all have the same 'base-type').

Overloading:

```
public class TestClass
{
    public void DoSomething( int a, int b ) {}

public void DoSomething( int a, int b, string x ) {}
}
```

Polymorphism:

```
public abstract class Base
{
    public abstract DoSomething();
}

public class A : Base
{
    public override DoSomething()
    {
         Console.WriteLine("I am A");
    }
}

public class B : Base
{
     public override DoSomething()
     {
         Console.WriteLine("I am B");
     }
}
```
